Title: Reactive tricalcium phosphate compositions and uses
Inventor: CONSTANTZ BRENT R
IPC: A61K6/838
Filed: 1995-10-31
Granted: 2009-06-16
Abstract: Methods for producing a room temperature stable, phase pure .alpha.-C3P  product, and compositions derived therefrom, are provided. In the subject method, a tricalcium phosphate source is heated to a temperature sufficient to convert substantially all of said tricalcium phosphate source to a substantially phase pure .alpha.-C3P product. The temperature of the resultant product is rapidly cooled to a temperature below about 700 ~C, resulting in a room temperature stable, reactive .alpha.-C3P product. The resultant .alpha.-C3P product may be milled to provide an .alpha.-C3P composition which may find use in the preparation of calcium phosphate cements.

Abstract: The invention concerns a mount for panel-shaped components, in particular glass panels, with a base element that penetrates through an opening in the panel-shaped component and immobilizes it, and a ball stud that has at its first end a ball element which is rotatably mounted in an opening of the base element which is complementary in form and function, and that can be fastened at its second, opposite end to a support structure, immobilizing the base element. The base element has an axial length such that at least one end of the base element projects out of the panel plane, the opening to receive the ball element being furthermore arranged in the region of that end. The base element has at least two base subelements that can be fastened to one another at their mutually facing radial surfaces in the radial plane of the base element that extends substantially through the center point of the ball element, thus enclosing the ball element.

Abstract: Disinfection arrangement for a dialysis machine consisting of a clean side and dirty side. The clean side comprises an inlet for water, a valve, a heat exchanger as well as a water vessel containing a heater. A feed conduit leads from the water vessel to a tube which is normally connected to the clean side of the dialyser but, during disinfection, is connected to a recirculation conduit via a valve in order to perform a first recirculation circuit. A second recirculation circuit is constituted by a recirculation conduit, a valve, a tube, which is normally connected to the dirty side of a dialyser, a return conduit as well as a pump. A heat exchanger heats up the fluid in the second circuit with the help of the fluid in the first circuit, which is heated up by the heater in the water vessel.

Abstract: The present invention relates to an electromagnetic piston engine capable of producing driving power by a reciprocal movement of a piston in a cylinder by electromagnetic force. The present invention has the objects to provide the electromagnetic piston engine which can do without a variety of resistance inherent in internal combustion piston engines, which reduces the weight corresponding to a rotary assembly portion to a smaller value even if a great output is produced, which can be readily employed together with power transmission mechanisms and so on for use with conventional internal combustion piston engines, and which has a high efficiency in enemy consumption. The electromagnetic piston engine is provided with the cylinder and the piston made each of a magnetic material as well as with as the cylinder electromagnet having the inner wall of the cylinder magnetizable to a one magnetic pole and with the piston magnetization unit for magnetizing a portion of the piston engageable with the cylinder to a single magnetic pole in a fixed manner.      The magnetization of the cylinder electromagnet generates magnetically attracting force between the cylinder and the piston to cause the piston to move in a one direction and thereafter magnetically repellent force to transfer the piston in the opposite direction. This series of the actions are repeated to provide a continual reciprocal movement of the piston.

Title: Aerodynamic mirror exterior shell
Inventor: OLSON M EUGENE
IPC: B60R1/06
Filed: 1998-08-19
Granted: 2002-09-10
Abstract: An aerodynamic exterior rear view mirror for motor vehicles that has low drag as a result of prevention of laminar boundary layer separation on the mirror head and subsequent turbulent wake size reduction. The vehicle mirror comprises an aerodynamic exterior shell having a continuously smooth surface with inboard and outboard trailing edges. The surfaces of the shell preceding the trailing edges can be either parallel or closing relative to the free stream airflow. A boundary layer control device that consists of a trip strip isformed on the exterior surface of the mirror head just upstream of the transition or separation point where the laminar boundary layer flow would transition to turbulent boundary layer flow with delayed separation or to complete separation absent the boundary layer trip strip. The trip strip, when correctly sized and utilized, will assist the laminar boundary layer to transition to turbulent boundary layer flow which reenergizes the boundary layer. The turbulent boundary layer is more stable and has more energy which will enable it to adhere to the surface and allow the airflow to continue to and separate atthe mirror head trailing edges. As a result separation is greatly reduced or eliminated which reduces the drag that would have been present, absent the boundary layer control device.
